Much worse than Cursor with Claude models in my experience. I'm getting many useless changes and things being reimplemented from scratch instead of moving files. Not impressed at all.
Sorry to give opposite anecdotes. It’s one of the things I find most irritating about AI right now.
It needs careful oversight, for if you're too generous with it, it'll happily add tons of code into your codebase that will make it horrendously difficult to understand and debug later. As capable as it is, I find it prudent to keep it on a short leash.
